[PATCH master] of: override existing reg property in of_fixup_reserved_memory

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

of_new_property doesn't care for existing properties and would happily
add a property that already exists leading Linux to trip over it when
creating the VFS view into the device tree.

Fix this by using of_set_property, which would delete an existing
reg property first, before adding it anew.
